';font-family:等线;mso-bidi-font-family:'times>

 

';font-family:等线;mso-bidi-font-family:'times>

在package.json中最重要的就是name和version字段。他们都是必须的，如果没有就无法install。name和version一起组成的标识在假设中是唯一的。改变包应该同时改变version。

';font-family:等线;mso-bidi-font-family:'times>';font-family:等线;mso-bidi-font-family:'times>

 

';font-family:等线;mso-bidi-font-family:'times>

';font-family:等线;mso-bidi-font-family:'times>

 

';font-family:等线;mso-bidi-font-family:'times>

“scripts”是一个由脚本命令组成的hash对象，他们在包不同的生命周期中被执行。key是生命周期事件，value是要运行的命令。
